Php7 Upgrading error

Hi..

I do not know whether you can help me with this issue or not.. let me explain the issue i am having with my wp site Bansurimusic.com

I am using https with php7, but when i upgraded to php7 some errors were coming in fronted and backend. The siteground support gentlemen disabled the opcache in php7 and those errors were corrected. Actually I want to have opcache feature in php7 enabled without any errors.

this was the error i was getting in the front end..
Warning: sprintf(): Too few arguments in /home/venugopa/public_html/wp-admin/menu.php on line 41
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 140662928427656 bytes) in /home/venugopa/public_html/wp-includes/functions.php on line 716

It looks like you have WP_DEBUG_DISPLAY set to "true" in your wp-config.php file. You shouldn't need to have that unless you are actively building and debugging your site. It's preferable to keep debug display set to false on a live site so your users don't freak out unnecessarily.

As for the Fatal error: Allowed memory size error, that means that the memory you have allocated to WordPress is insufficient for the tasks you're giving it. I would recommend increasing that to a full gigabyte so you never see that nonsense again. Add the following to your wp-config.php file:

Please be sure that any defines or constants you add to your wp-config.php file are added before the line that says /* That's all, stop editing! Happy blogging. */. Anything added after that can break your site.
